"It is one of the objects of the invention to providean improved arrangement of parts by the use of which the leading edge ofthe closure member upon an opening operation is given first an obliquemovement edgewise and outwardly away from the window frame so as .to cutdown to a minimum the frictional engagement of the movable .closuremember on the stationary frame parts. In the preferred construction, theclosure member is provided with weatherestrips along its side edges inposition to engage suitable portions of the window frame assembly, theare rangement being such that the oblique movement of the closure memberat the start of .opening operation carries the Weather-strips out ofposition for operative engagement with the frame so that the closuremember moves easily and smoothly and the wear on the weather-strips iskept to a minimum. In the arrangementasillustrated, W ther-strips areprovided both .alon the side edges of the closure member and along theside bars of the window frame, one of such sets of weather-strips beinginchannel ortgroove form so as to receive a rib or tongue portion of thecooperating strip therein :for making a tight joint at each edge of theclosure :member. In this arrangement, the oblique movement of theclosuremember at the start of the opening operation is particularlyhelpful, since 1it;assu r es the benefit of a highly effective jointwhen the window is closed while at thesame time permitting the closuremember to be moved easily out prove arrangements of this type in sundry,de-

tails hereinafter pointed out. The preferred means by which theseveralobjects have been attained are illustrated in the accompanyingdrawings and are hereinafter ;specifically described. That whichIbelieve to. be new; and de sire to cover by this application :is setforth in the claims.

For.closin :thewiudow-oneni aa p eceofnl-ate lass 32-9 i employedprovided-se its lower :edge

mounted on the rods 26. Just above the collars 34, other collars 35 areslidably mounted on the rods 25, coiled springs 35 being interposedbetween the collars for holding the collars 35 normally raised to thelimit of their motion with respect to the collars 34. Links 31 arepivotally connected at their forward ends with the collars 35 and attheir rear ends with the downward extension 3|, the pivotal connectionwith said extension being effected by means comprising lugs 38. Thearrangement is such that when the collars 35 are moved downwardly towardthe collars 34 from the position shown in Fig. 4 to the position shownin Fig. 2, the downward exten-, p

sion 3| and the plate glass 29 connected therewith are moved backwardlytoward the right in;

said figures.

As is best shown in Fig. 2, the lower edge of the plate glass 29 isprovided with a rubber gasket 39 which is secured in position by screws40 taking into a cross bar 4|. The arrangement is such that when theplate glass is moved to the upward limit of its motion the gasket 39 hastight engagement with the frame bar I9 so as to seal the joint betweenthe glass and the bar.

The means for moving the glass 29 upwardly. and downwardly with respectto the frame bar l5 comprises a spiral pinion 42, fixedly connected withthe screw 28 and meshing with a spiral gear 43 fixedly connected with aspur pinion 44 which in turn meshes with a spur gear 45 driven by acrank handle 46 positioned at the front face of the housing 23. When thegear 45 is driven by means of the crank, the screw 28 is rotated,serving to move upwardly or downwardly a nut 41 having a threadedconnection with the screw, the direction of movement of-the nutdepending of course upon the direction of rotation of the 1 wardlytoward the right in Fig. 2 for bringing the gasket 39 into sealingengagement with the bar I9 at the end of the upwardmovement of theglass. -When the glass thereafter is moved downwardly again by a reverserotation of the screw 28, the springs 36 insure thatthe links 31 shallbe biased to the limit of their motion as soon as the pressure on thecollars 35 is relieved so as to cause the downward extension 3| and theglass definitely to move forwardly for carrying the gasket 39 out ofengagement with th bar I9.

' The means for sealing the Window at its upper edge comprises a stripof sponge rubber 49 held in position by a sheet metal member 59. Atopposite sides of the window, the side bars I1 and I8' are provided withchannel members 5| opening inwardly, with a grooved sealing member 52mounted at one side of each of the channels in position for engagementwith a cooperativesealing'member 53 mounted on the glass in the form :7

of a rib or tongue. In the arrangement shown, the grooved sealing memberis formed largely of felt, while the ribbed member 53 is bent. into formfrom sheet metal so as to grip the edge of ,the glass for presentationof the rib effectively to the groove. In the construction illustrated,the upper end portion of the front flange portion 54 of each of thechannel members 5| is obliquely disposed so as to cooperate with thelinks 31 for moving the glass backwardly toward the frame member l5 whenthe glass approaches the upper limit of its movement.

By the use of my improvements, I have provided a highly usefularrangement. When the window is closed, the opening is completely sealedso as to prevent the entrance of water, for example, when employed inconnection with a boat. I he weather strips are arranged so as to resista high degree of pressure without danger of any water seeping throughany of the joints about the closure member. When, however, the closuremember is moved edgewise out of closure position, the closure member isgiven an initial movement facewise for carrying the weatherstrips out ofengagement with each other so as to permit easy movement of the closuremember and so as to keep to a minimum the wear and tear on theweather-strips and the operating parts.

While I prefer to employ the form and arrangement of parts as shown bythe drawings and as above described, my invention is not to be limitedto such arrangement except so far as the claims may be so limited, itbeing understood that changes might well be made in the form andarrangement of the parts without departing from the spirit of theinvention.-
